The Ray-Ban Balorama RB4089 sunglasses are a 1967 icon of forerunners' style. Cozy and elegant, this is a model of sunglasses especially loved by unique personalities and still remains hip today. Propionate plastic forms the contoured pillow eye shape and wrapped fit on these sunglasses. They feature crystal lenses and come polarized. This model has double rivets and the Ray-Ban signature logo finishes the temples.Excellent choice for someone who leads an active lifestyle, but does not especially like the aggressively wrapped sunglasses that are so common. Quality is unequaled in the materials used in every part of these sunglasses. The nylon frames wrap gently around the eyes to provide excellent protection, while still maintaining a very traditional look. The polarized glass lenses are excellent at reducing eyestrain and fatigue, block 100%UV (ABC,) and are great for improving contrasts. Polarized lenses are ideal for use on water or in any other high-glare situation. Includes a carry case.
